How can drivers ensure the steering components are functioning properly?

To ensure the steering components are functioning properly, turning the steering wheel and noting any unusual resistance or free play is crucial. This action helps drivers to assess how the steering system responds and feels while being operated. If there is excessive resistance, it may indicate that the steering gear or linkage is failing, while significant free play could suggest wear or looseness in the system, both of which can compromise safety and control of the vehicle.

The other options, while they involve important aspects of vehicle maintenance, do not directly relate to the functionality of the steering components. Checking tire pressure, for instance, is vital for overall safety and handling, but it does not evaluate the specific condition of the steering system. Similarly, examining engine oil levels and inspecting the headlights are unrelated to steering performance and would not provide insight into the health of the steering components.
